| Abstract | Electricity plays a major and essential role in operating many electrical and electronic home appliances used on daily basis. Electricity is an energy carrier since it moves energy from one place to another and it could be used for so many tasks. Apparently, there has been a growth in the demand for electricity in the contemporary society. Energy conservation and efficient use of electricity are important goals for everyone. Not using energy or electricity in a sustainable manner could lead to a real crisis for future righteous existence of human being. A digital power meter to measure power consumption of home appliances could be an ideal solution for this. These power meters are already available in the market and they are supported with different technologies like wireless, Bluetooth etc. This report focuses on digital power monitoring device with power line communication (PLC). The complete system is divided into two units and they are measuring unit and transmission unit. Measuring unit measures the voltage and frequency applied to the appliance (or voltage drop across the load), current through the appliance, power factor and most importantly the power consumption of the appliance when the appliance is plugged in to the device. Device is plugged in to the power outlet and appliance is plugged in to the device. Supply AC voltage signal is reduced by the simple voltage divider circuit and the reduced signal is fed to the Microcontroller. ACS712 Current sensor module is used to sense and feed the AC current signal passing through the appliance to microcontroller. ATMega328P microcontroller with an Arduino Uno board is used for sampling and fast analog to digital conversion. 16x2 LCD is programmed to display the measured and calculated parameters. Mamba shield – narrow band power line communication modules are used to establish communication between two power outlets. One shield transmits these data displayed on the measuring unit display and the other shield receives them. The received data are again displayed on a 16x2 LCD available in the transmission unit at the receiving outlet. In order to program this LCD, separate Arduino is used. Two Arduino boards are used with these 2 PLC modules (one for each). Altogether, 4 Arduinos are used in the project (transmission unit - 2, measuring unit - 2). Arduino IDE is used to program the Arduinos used in the project. It is a cross-platform application written in Java and is derived from the IDE for the Processing programming language and the Wiring project. The main objective of this project is to apply the knowledge in electrical, electronic and microcontroller programming which are key aspects in engineering sector. |
